Bitcoin is a digital currency and electronic payment system operating over peer-to-peer network on the Internet. One of its most important properties high level anonymity it provides for users. The users are identified by their addresses, which random strings in public records transactions, blockchain. When user initiates Bitcoin-transaction, his client program relays messages to other clients through network. Monitoring propagation these analyzing them carefully reveal hidden relations. In...

Proteins are insulating molecular solids, yet even those containing easily reduced or oxidized centers can have single-molecule electronic conductances that too large to account for with conventional transport theories. Here, we report the observation of remarkably high conductance states in an electrochemically-inactive protein, ~200 kD αVβ3 extracelluar domain human integrin. Large current pulses (up nA) were observed long durations (many ms, corresponding many pC charge transfer) at gap...

We analyze gene coexpression network under the random matrix theory framework. The nearest-neighbor spacing distribution of adjacency this follows Gaussian orthogonal statistics (RMT). Spectral rigidity test prediction for a certain range and deviates afterwards. Eigenvector analysis using inverse participation ratio suggests that bulk eigenvalues is consistent with those real symmetric matrix, whereas few are localized. Based on these IPR calculations, we can divide in three sets: (a)...

The relativistic generalization of the standard map is introduced, based on problem particle acceleration in electric field an electrostatic wave packet. It shown that diffusion is, general, less effective than for nonrelativistic particles. In ultrarelativistic case chaotic motion appears form intermittency.

Human interaction networks inferred from country-wide telephone activity recordings were recently used to redraw political maps by projecting their topological partitions into geographical space. The results showed remarkable spatial cohesiveness of the network communities and a significant overlap between redrawn administrative borders.

Abstract Recently, numerous approaches have emerged in the social sciences to exploit opportunities made possible by vast amounts of data generated online networks (OSNs). Having access information about users on such a scale opens up range possibilities—from predicting individuals’ demographics and health status their beliefs political opinions—all without limitations associated with often slow expensive paper-based polls. A question that remains be satisfactorily addressed, however, is how...

In the absence of other tools, monitoring effects protective measures, including social distancing and forecasting outcome outbreaks is immense interest. Real-time data noisy very often hampered by systematic errors in reporting. Detailed epidemic models may contain a large number empirical parameters, which cannot be determined with sufficient accuracy. this paper, we show that cumulative deaths can regarded as master variable, parameters such basic reproduction number, size susceptible...
